Condensing boilers are efficient because they convert more gas into usable heat, and the outcome is a lower operating costs. They have a highly effective heat exchanger that captures and reuses wasted heat.
Types of condensing boilers
There are two different types of condensing boilers:
1. Back boilers use a fireplace for hot water and central heating and,
2. Combi boilers can heat hot water on demand, and they are usually cheaper to install.
The gases emitted from a condensing boiler are cool and a fan makes up for the lower convection flow. The exhaust appears as a continuous flow of steam. If the installer is fitting a condensing boiler to an existing system, the system will need to be power-flushed.
Condensing boilers were first presented to the general public in the 1980’s, and they are becoming a popular alternative to conventional central heating systems as they offer more energy, have simple controls, and save space. Unlike conventional boilers, a condensing boiler does not need a hot water tank. Conventional boilers use timers for hot water, but condensing boilers produce hot water when the faucet is turned on.
Condensing boilers can be up to 15 percent more efficient than conventional boilers, and the energy savings can be even higher when compared to older boilers. The cost of a condensing boiler can usually be recouped in a few years after upgrading the boiler.
General Maintenance Issues
A condensing boiler needs regular maintenance, and a qualified installer, like ProPlumbUK, should inspect the unit at least once a year. We can make sure that the boiler is operating efficiently and safely. Some boilers need to be serviced on a more frequent basis, so it is best to follow the manufacturer’s service schedule. We service condensing boilers all over Kent including Bromley, Sevenoaks, Orpington, Petts Wood, Chislehurst, Beckenham, Bickley, Keston, Otford and St Paul Cray to name but a few so please don’t hesitate to call us on 0800 298 2639 and we’ll be happy to help.
General Maintenance Inspection
General maintenance is not expensive, and a qualified technician may only need to make sure that the condensate drain is functioning properly. A conventional boiler will release excess heat into the atmosphere, but a condensing boiler will reuse any excess heat. The unit will absorb as much heat as possible while running efficiently.
More Venting Options
In addition to lower energy bills, a condensing boiler can help you reduce your carbon footprint. Such boilers use less fuel to heat water, and the savings usually amount to at least $100 a year. In addition, they have several venting options. The unit could be vented through a sidewall, or it can be vented through a ceiling. The forced-draft design means that the building will have more usable space.
Signs of a Malfunctioning Boiler
There are several signs that a unit may need our condensing boiler repair service. A lack of hot water is the first sign of a malfunctioning boiler, and an orange or yellow flame can also be a sign that the unit needs our service. The unit could need servicing if the boiler pressure remains too high or low for a prolonged period. Any ticking or clanking noises are also a bad sign.
Preventing Frozen Pipes
A condensing boiler can freeze when the weather is cold. Keeping the pipes warm should always be a priority. The thermostat should run continuously when the house is cold. When you are not home, the heat should be set at a low temperature. It should never be completely turned off. If the pipes freeze, you can put a warm water bottle on the frozen pipes. You can also pour warm water on the pipes. You may have to repeat the process several times.
If the pipes freeze whenever the temperature drops, you should contact us. We might need to install insulation around the pipes. A condensing boiler repair and installation specialist like ourselves can handle large and small maintenance issues. Do not wait until the temperature drops below freezing. Let a boiler specialist handle your new installation or repairs for complete peace of mind.
